Application filed January 24, 1914. Serial No. 814,050.

To all whom t may concern.'

Be it known that we, CHRIST SPECHT and THOMAS WILLIAMS, citizens of the United States, residing at Punxsutawney, in the county of Jefferson and State of Pennsylvania, have invented certain new and useful mprovements in Devices for Converting Motion, of which the following is a specification.

The present invention relates to an electrically operated pump, and more particularly to a novel form of gearing which embodies new features of construction whereby the rotary motion of an electric motor can be readily converted into the reciprocating motion necessary to operate the pistons of an ordinary water pump.

A further object of the invention is to provide a device of this character which is comparatively simple and inexpensive in its construction, which can be utilized in connection with the conventional forms of electric motors and reciprocating water pumps, which can be readily assembled or taken apart, and which will withstand the wear and tear to which such devices are subjected when in use.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of an electrically operated pump constructed in accordance with the invention. Fig. 2 is a top plan view of the same. Fig. 3 is a transverse vertical sectional View through the gearing. Fig. 4 is an enlarged longitudinal sectional view through the upper end of the standard and the axle which is mounted thereon. Fig. 5 is a detail perspective view of the axle.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

Referring to the drawings which illustrate a preferred embodiment of the invention, the numeral 1 designates an electric motor which may be of the conventional constructon and is bolted or otherwise rigidly secured to a suitable bed 2.

The numeral 3 designates a two cylinder pump which may also be of any conventional construction and is bolted or otherwise rigidly secured to the bed 2 in an opposed relation to the electric motor 1. This pump 3 has the usual equalizer 4, and the piston rods 5 thereof are connected at their outer ends to cross heads G which are slidably mounted within the guideways 7.

The shaft 8 of the electric motor terminates in a beveled pinion 9 which projects between and meshes with a pair of large beveled gear u heels 10. These large gear wheels 10 are journaled upon opposite ends of a shaft 11 which is mounted upon a standard 12, the said standard projecting upwardly between the gear wheels 10 and being formed with an enlarged base l2a which is bolted or otherwise made rigid with the bed 2 at an intermediate point between the motor l and pump 3. The middle portion of the axle l1 has a square or polygonal formation as indicated at 11a and is seated within a corresponding notch in the upper end of the standard 12, a cap piece or yoke 14; being fitted over the top of the angular portion of the axle and bolted at 15 to the standard so as to retain the axle rigidlyin position. lt will also be observed that this axle 11 is provided with an oil duct 16 opening through the top of the axle at the middle thereof and opening downwardly through the end portions of the axle upon which the large gear wheels 10 are journaled. The cap plate 14 has an opening registering with the upper end of the oil duct 16, and an oil pipe 17 has the lower end thereof fitted within this opening. The upper end of the pipe 17 projects above the main gear wheels 10 where it is provided with an oil cup or reservoir 18. Suitable bushings 19 may be interposed between the ends of the axle 11 and the gear wheels 10 to reduce the friction.

Each of the main gear wheels 10 is provided with a wrist pin 20, the two wrist pins having a diametrically opposed rela-- tion with respect to the axle 11.

A boxing 21 is loose upon each of the wrist pins, and pitmen 22 connect the boxings 21 to the pivot pins 23 of the respective cross heads 6.

Oil cups 24 are threaded or fitted in the When the motor 1 is being driven, thel motion imparted to the beveled pinion 9 thereby Will rotate the tWo main gear Wheels 1.0 in opposite directions, although the said Wheels will turn at the same speed so that the Wrist pins 2O thereof Will always have a diametrically opposed relation. This opposite rotation of the tWo Wheels l Will alternately move the piston rods 5 of the pump in and out so as to operate the pump in the required manner and produce a continuous flow of Water. Effective means has been provided for keeping the various moving parts of the gearing properlylubricated, and by removing the nuts 29 and Washers 28 the main gear Wheels 10 can be taken 'from the axle and the device quickly dis- Vmounted so as to admit of any necessary repairs being readily made.

A resistance box R is connected to the motor 1. In the presentinstance the resistance comprises thirty-six lamps 30 Which are arranged in nine series S of four lamps each. An independent switch 31 is provided for each series S of the lamps so that 'i any desired number of the series of lamps can be thrown into the circuit With the motor. In this manner the pump can be run at any speed. When it is desired to increase the speed, an additional switch 31 is Copies of this patent may be obtained for closed to put in another series of lamps, since the speed of the motor lncreases as the resistance increases. The various lamps are arranged in a number of series, so that' if' in the upper end thereof, a transversely disposed axle having a polygonal intermediate portion which is seated Within the' angular notch of the standard While end portions of the axle project upon opposite sides of the standard, a yoke piece fitted over the polygonal intermediate portion of the axle and secured to the standard, a pair of oppositely revolving beveled gear Wheels journaled upon the ends of the axle, a drive shaft arranged at right angles to the axle and projecting between the gear Wheels', bearings for the drive shaft, a pinion applied to the drive shaft and meshing With the tWo gear Wheels, a Wrist pin projecting fromeach oi the gear Wheels, a pair of independent cross heads, and pitmen connecting the Wrist pins to the respective cross heads.

In testimony whereof We aiiix our signatures in presence of tvvowitnesses-- CHRIST SPECHT. THOMAS WILLLIAMS.
